L02 - Needs challenge Activity #73

Open lwasser opened 8 years ago

lwasser commented 8 years ago

There is no wrap up challenge in Lesson 02 - we should have them work with another file - figure out the time stamp format and convert / plot. Perhaps we can have them look at 15 minute english (boring) OR data for another set of variables altogether that is related. Or for another site like SJER.

@mjones01 this lesson still has no challenge activity. Did you have anything in mind? We could have them work with data from NEON potentially?? FIU data for harvard forest which i think i have somewhere on my computer already. thoughts?

Alternatively we could have them import and convert/ set time for the Day length data as it is already in the data set.

Import DayLength_Petersham_Mass_2015.csv Ensure that the time and data is in POSIXlt class and with the correct time zone. Hint: metadata in DayLengthSource_MetaData.txt Plot daylength by date using qplot.

(I chose 2015 as it is the only .csv file and we don't specifically teach read.txt -- maybe a good Data Tip to add to L00).

Sure - have you looked at that data? Importing it isn't straight forward because month is the COLUMN heading and each column has an uneven number of rows. I have code to import it - but it's not what we've taught.

I love the idea in theory but not sure in practice.
